IMPROVEMENT lN HOSE-COUPLINGS.

" Specification forming part of Letters Patent No. 164,8 16, dated June 22, 1875 application tiled March 9, 1875.

To all whom it may concern Be it known that I, EDWIN DAYTON, of Meriden, in the county of New Haven and State of Connecticut, Ahave invented a new Hose-Coupling; and Ido hereby declare the following, when taken in connection with the 'accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot' the same, and which said drawings constitute part of, this specification, and representa longitudinal section as""""ap plied to a section of hose.

This invention relates to an improvement in the construction and attachment of coup-` lin gs to hose 5 and itcons'i-sts in construct-ing the parts Ot` the cduplin g with a hollower;ternallyl threaded plug to enter the end of a section ot' hose, andwith a flange topass over the said end, combined with an internally threaded socket ot' larger external diameter than the internal diameter Ot the hose, inserted into the hose, then theplug screwed into said socket to draw said lia-nge Onto the hose, to clamp the hose between said socket and ange, as more fully hereinafter described.

A is the male and B the :t'emale part of the coupling, the part B swiveled in the usual manner; C, the plug, formed upon or attached to the part of the coupling proper. The external diameter of the plug is substantially that ofthe interior of the hose to be coupled, and on the interior a screw-thread is formed-the interior made as large as may be consistent with the strength required. On this plug, or attached thereto, is a flange, D, forming an annular space, d, around the plug, the internal diameter of the flange substantially that ot the exterior ofthe hose, so that as the plug passes into the end ofthe hose, the tlan ge will pass over the outside. E is the socket, its eX- ternal diametergreater than the internal diameter of the hose, and preferably of less diameter at one end than at the other. This socket is threaded upon its inside to correspond to the thread on the plug. The socket Hlil is inserted into one end of the hose a short distance from the end, as seen at the left hand in the drawing, then the plug is screwed into the socket, the flange D passing over the end Ot' the hose, as seen at the right hand in the drawing, until the hose is firmlyr clamped between-the llange and socket, as shown. This secures the coupling to the hose in the most perfect manner.

I clairn- The hollo\ v-threaded plug O, formed upon or attached to the respective parts ot' the coupling, and the iiange D on said plug combined with the socket E, substantially as described.

EDWIN DAYTON.
